Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: A device and method for determining defect sectors on an optical disc receives writing commands and data by a processor, and saves the writing data in a memory. An error correction code (ECC) encodes the writing data into encoded digital signals, and the encoded digital signals form modulated digital signals by a modulation device which are saved back into the storage. The processor controls a pick-up head to write and read the modulated digital signals. A comparing unit generates a number of errors by comparing the modulated digital signals before and after writing. The defect sector is directly determined if the number of errors are low or high. The modulated digital signal is decoded to determine the defect sector based on the failure or success of decoding if the number of errors lie in the middle of the range.
